Once upon a time there was only one firm on the lips of any business's IT team when it came to company phones – BlackBerry.
BlackBerry is still a big player in the enterprise market but the rest of the pack is hot on its heels, with the likes of Apple, Samsung and Microsoft all eager to get a piece of the business pie.
In no particular order, here are the top 10 smartphones for business use and business users:
We're kicking off our top 10 with the new handset from the firm once synonymous with business handsets – the BlackBerry Z10.
BlackBerry has always been a firm favourite in the business arena, but recently people have been switching over the Apple and Android offerings.
The Z10 aims to win back the business market with the firm's new operating system, BlackBerry 10, sitting at the heart of the handset.
It's a fully touchscreen offering so if you can't live without the QWERTY keyboard set up you'll have to wait for the BlackBerry Q10 to land in stores, or check out one of the older handsets below.
The big advantage with the BlackBerry Z10 is its excellent support for business users.
IT departments can take control of the handset using BlackBerry Enterprise Service 10 (BES 10), with security provided by BlackBerry itself ensuring all your emails and messages are fully encrypted.
The Z10 has a feature known as BlackBerry Balance which allows you to flip quickly between work and personal profiles on the handsets, allowing you to keep the two separate with work controlling the business side while you have full control over your own area.

More and more businesses are turning to Apple's smartphone offers, and while it produces great looking, powerful devices they certainly come at a price.
The iPhone 5 is the latest in Apple's phone line up, bringing a slimmer design and larger display to a handset which continues to turn heads in every circle.
Apple now offers a wide range of enterprise resources on the iPhone 5 with support for SSL VPN and data protection APIs, enabling third party apps makers to produce fully secure solutions.
On the topic of apps, the iPhone family is probably best placed when it comes to business focussed software, with thousands of applications available on the App Store aimed at making work easier.
Then there's Siri, the helpful personal assistant who listens to your voice and brings you whatever you need, even if it is to check the footy scores.
The iPhone 5 runs Apple's latest software which goes by the name iOS 6, and while it may be starting to show its age when compared to the rapidly evolving Android, it's certainly a platform with solid foundations you can rely on.

Samsung Galaxy S3
Its super slick Android Jelly Bean interface, responsive and bright 4.8-inch HD display and powerful quad-core processor means the Galaxy S3 has the vital statistics to make it a great business tool.
Add to that its highly adaptable email and note-taking applications, a whole host of connectivity options and on-device encryption to make sure all your top secret files are safe and secure, and you'll want to seriously consider this top selling device.
Android is far more adaptable and customisable than Apple's iOS system, meaning that if you have some technical boffins in your ranks you will be able to customise the Galaxy S3 to suit your firm's needs.
As with the iPhones, the Galaxy S3 is a premium handset carrying a premium price tag and you'll need to ensure your bank balance can cope with the expenditure if you do plump for this device.

Nokia Lumia 920
Unsurprisingly, Windows Phone 8 plays nicely with its computer based brother – although companies running Macs may want to opt for the iPhone instead.
The unfussy Live Tile display on the home screen keeps things simple, allowing you to access your emails, messages or call log quickly, and the intuitive interface makes it an easy system to learn.
The Lumia 920 has the largest screen of the current Windows Phone 8 crop at 4.5-inches, which comes in handy when viewing documents and long email chains.
Microsoft's fully functioning Office Suite for mobiles - something which is currently only available on Windows Phone – is installed on the handset, making last minute amendments on the way to a meeting easy.
It's a bulky handset with some considerable weight, but if you can cope with that you'll enjoy the Nokia Lumia 920's powerful offering.

BlackBerry Bold 9790
If you can't wait for the BlackBerry Q10 to arrive but desperately need a smartphone with a QWERTY keyboard, then look no further than the BlackBerry Bold 9790.
It may not have the blockbuster specifications of some of the other handsets featured in this list, but it's strength is in its business acumen – an area which the Bold 9790 and BlackBerry devices in general thrive.
The display is just 2.45-inches in size, but it is fully touchscreen and the complete QWERTY keyboard trumps any on-screen offering when it comes to speed and accuracy of input.
The feather in BlackBerry's cap is its extremely secure enterprise server, which sees all your emails routed through the firm's Fort Knox style system, ensuring all your sensitive information is kept well out of sight.
With 8GB of internal storage and the option to expand on this with a microSD card, there's plenty of space to save all your important emails and documents on the device, giving you access anytime, anywhere.
Its slender frame, chrome highlights and rubberised rear provide a premium look and ergonomic design which can fit snugly into a shirt pocket.
There are some limitations, however: the screen is very small so those with poorer eye sight may struggle to see what's going on, while the application offering is extremely limited.
